Be it. known that MATH HENNEN, citizenv ofthe UnitedStates of America,residing aty 'This invention relates in general to` im#v `y provementsin 'the construction and operation of vagriculturalimplements and to'del vices for transporting such implements,"andl relates morespecifically to an' 'improved'attacher'and carrier for agricultural.imple-1 mentsv such as p lows,l

rows.'

*cult-ivators, and *harn An object of the invention is to provide anVimplement carriage which is relativelyl simpleand compact inconstructionlandefficient in operation.f 'Another object of theinvention is to provide a carrierfor agricul-4 tural. implements such'as plows,` cultivators, and'harrows, which will permitl greatflexibility in attachment,v position-ing and adjustment of the implementso as to secure maximum efficiency in operation.`

Some of the more specific objects of thev invention are as follows: toprovide an im# plement carriage vwhich will permit reduction of theimplementstovtheirsimplest form: to` provide a" singleffcarrier"adaptedfor interchangeable' attachment "toi" and cooperation with .variousimplements such asf mold board plows, side hill plows, vmiddlestubbleshaver gangs, stubble digge'rj gangs, listers'anddiskharrows'a'to provide' an implementcarriage adapted for attachment toand co-operationv with almotor driven'tractor: to provide an implement'carrieroper-A-r able in conjunction with-a tractor by asingle edYtransportation of implements `associated therewith over roads and thelike: toprovide other improvements in implement attachers and carrierswhich will .facilitate manufacture and operation thereof.

,During normal operation. the :implement carriage is Apreferablyattached :to a--traetor in such lmanner asv to permit ready manipwlation of :the tractor controlling .levers and ofthe steering Wheel.26.,` fromitheaoperator-s seat 7. The plow 4er other implement -Whichis to be drawn, has .a forward portion-of lits draft beam :27 `securedto a drawbar Q4, and has a rear portion Vof :the Abeam QT-'secured -to-the loWer end Aof a .lifting link As the :tractor advances, :theimplement "carriage .simultaneously advances dragging the implement,'With it. y

As efficient operation -of `most :implements is -dependent4uponaccurate, application -o'f the pulling force and upon properpositioning k'of fthe' '.-implement #relatively lto the ground5 :it isdesirable to adjust thegposition of the ltransverse]draw 'bars .Q4 so.as :to properly apply the draft .and .'to level Athe `impilement. `Suchadjustment of (the draw bars 24 may be effected vby manipulation andadjustment `rof the tilting'levers 16 relatively to :the fixed :notched.sectors 18. flBsy jreleas-` ing .the lock -of ieither lof Athe levers:1.6, Aand ymoving .the released ilever forward or ba'okward, thecorresponding ypivoted push arm will be swung aboutv its pivot 23thereby .v

moved` The elevation and transverse angularity of the draw bars 24 maythus be varied within the limits of the notches in Athe sectors 18, toaccommodate one or more implei'nents attached to the draw bars and toproduce'efficient application of the pullingyforce. The hook pivots 23have sufficient lateral clear,

anceto permit tilting of the arms 5y during tilting of the draw bars 24and thelooseness between other connected elements `is also sufficient topermit suchtilting without in:

juring the parts. If the degree oflswing of the arms 5 as limited by thenotched sectors 18, is insufficient to permit proper 'disp'osi-- tion ofthe implement. draft beam: 27, the links 13 may be adjusted'in lengthor, the

hitch bars 32 maybe turnedup .side down, inorder -to increase the rangeof adjustment.-

The compression springs 28 protect the levers 16 andthe elementsassociatedtherewith, aga-instinjury Vdue .to sudden or Leatreineapplication of upward pressures against the draw bars 24, thesespringsybe-V ing automatically compressed by suchpressures withoutdisplacingt-he links13.y i Y f The rear portion of4 the implement' may"backward, the ,corresponding pivoted support 33 will be swung `about itspivot on the frame 3, thereby raising lor lowering theadjacent end' ofthe transverse cross shaft 39 and tilting this shaft. By simultaneouslymanipulating both lifting levers 17, the cross shaft 39 may be moved up'or downto paral lel positions. The connections between the ends of theshaft 39 andthe supports 33,v`

" are such as will permit relative tilting, withi out injuring theparts. `The elevation Aand suspended from the cross shaft 39, the rear fportion of the implement may be raised and, lowered relativelyto-'fthegroun`d, independtransverse angular position of the 'cross shaft39 may thus be varied within'thelimits of the notches in the sectors 19to properly position one or more implements associated with the shaft,relatively to thegrou'iid.l Thel compression springs 38 protect they:levers 17 and the elements associated directly,

therewith, against injury due to sudden or eXtreme upward pressuresacting upon the shaft 39, and also permit application of a predetermineddownward Apressure upon the implement when coacting with the ground. i
